EliSowash writes: "Nokia is proposing “a material attachable to skin, the material capable of detecting a magnetic field and transferring a perceivable stimulus to the skin, wherein the perceivable stimulus relates to the magnetic field.” The material would react to magnetic signals emitted by a nearby electronic device, such as a smartphone, and that magnetic field would interact with the tattoo, causing it to vibrate.

Sounds to me like more of a 'patch' than a 'tattoo' but that's the language they used in the patent and not really the point.

So...would you? Are you so connected that you'd attach a notifier directly to you? And (dare I ask) just where would you put it??"
